Since these events are independent, you add the possibilities
the number of cards less than 9 is 32
the number of spades is 13
there are 52 cards in a deck, so you put those numbers over 52
32/52 + 13/52 = 45/52
the answer is 45/52
If you are looking for √16, you are looking for the square root of 16. The square root of a number is defined by what number multiplied by itself will get you.
x^2 (a number squared) = 16.
√16 = x.
Let's try from numbers 1-5 for a square.
1x1 = 1
2x2 = 4
3x3 = 9
4x4 = 16
√16 = 4.
I hope this helps!

Answer:
144pi
Step-by-step explanation:
The formula for the volume of a cylinder is base*height
The base of a cylinder is a circle, so it's pi*r^2
r = 6, so pi*r^2 is 36pi
height is 4 so 36pi*4 is 144pi
